Leguizamo Visits ER

ER producers are racing to fill in the casting gap left by the recent departure of longtime star Noah Wyle, and the latest addition to their roster is comedian John Leguizamo.

The Emmy-winning 41-year-old will play Dr. Ernesto Clemente, a new supervising physician who brings "cutting-edge technology" and a bunch of big ideas to County General. Leguizamo will appear in 12 episodes of the show's 12th season, which premieres on Thursday, October 20.

Leguizamo will appear alongside fellow newcomer Kristen Johnston (3rd Rock from the Sun), who comes to ER in a recurring role as new nurse manager Eve Payton. Eve's intentions are to bring order to the chaotic department, but of course things will not be as easy as she might hope.

In addition to his one-man HBO and stage show Freak, Leguizamo has appeared in movies such as Ice Age, Summer of Sam, and Land of the Dead. He starred in a CBS pilot earlier this year, but the show was not picked up
